Abstract (en)
[origin: EP1063248A2] A method for preparing a polyurethane flexible foam by reacting an organic polyisocyanate with a polyol in the presence of urethane catalyst, water as a blowing agent, optionally a silicone surfactant, and a cell opener characterized in that the cell opener comprises the reaction product of a C1-C20 hydrocarbyl group-containing organic acid anhydride and 2,2,4-trimethyl-1,3-pentanediol monoisobutyrate, optionally reacted in the presence of a tertiary amine urethane catalyst.
